I’ve spent a couple of days recently as a Room Guide in our Tunny and Colossus galleries @tnmoc . Lots of fun powering up and demonstrating these machines, with such a great story to tell. Quite a contrast to the ‘modern’ computers here from the 1980s!

A complex, 10-month engineering project to crack senior German military radio communications came closer to fruition -1944: Colossus, designed by Tommy Flowers based on plans by mathematician Max Newman, was delivered to Bletchley Park & assembled by Harry Fensom and Don Harwood.

The second issue was the monitor was too dim. Nothing seemed amiss at the monitor end of things, so swapped the 7486 and 74S74 that drive the video from the mainboard. Swapped those and screen is great now!

Some nice fault finding yesterday @tnmoc. This PET would not boot, test showed UD7 ROM failing and then test stopping at IRQ test. Only difference with that ROM is CS being fed from a 7425 and 74LS00 - swapped those and the machine sprung into life 😀. #CommodorePET #Commodore

@TheDigitalOrph @tnmoc @MuseumComputing Thanks again for hosting me (and for lunch!). Commodore Geek me especially loved your Commodore items!

Brilliant visit to @MuseumComputing kindly hosted by @TheDigitalOrph. Some really nicely curated displays amazingly well presented. Great to exchange ideas + plans and enjoy a nice spot of lunch.

@Lord_Arse Definitely an iconic demo - we have a copy running every day at the museum (@tnmoc) on one of our Amigas 😀.
